With just two episodes left to go until Game of Thronesleaves our screens forever, fans are dissecting every little thing they can ahead of the finale.

Although the Night King and the army of the undead are done and dusted (literally), the North still has one more enemy to face – Cersei Lannister.

But while the end result of the Battle of Winterfell was definitely not what we were expecting, fans have some interesting thoughts about how the North could take back King’s Landing from Cersei Lannister and Euron Greyjoy.

Clare Stephens and Holly Wainwright debrief on the latest episode of Game of Thrones on the Mamamia Recaps podcast. Post continues after audio…

In this week’s episode of Game of Thrones, Daenerys Targaryen’s dragon, Rhaegal, was shot out of the sky and killed by Euron Greyjoy and the Iron Fleet.

It was… traumatic.

But according to a popular fan theory, Drogon, Rhaegal and Viserion might not be Daenerys’ only dragons.

In a trailer for next week’s episode, the second-last ever of the series, many fans noticed Euron’s terrified expression as he looked up into the sky.

What is he looking at?

But while Euron could have been looking at, well, literally anything, some fans have connected the moment in the trailer to a resurfaced theory about Daenerys' dragons – and to be honest, it's pretty mind-blowing.

"This theory says that in the fifth season, when Drogon spends almost a whole season gone, he's actually laying eggs and is, in fact, a female. That's why he was burning fields full of sheep, goats and etc. to feed the baby dragons," Reddit user Justzxcvbnm wrote.

"He's the only one who disappeared, the only one who drove herds and took them all like roasted sheep. What made me rethink this theory was [seeing the] episode five promo, where Euron Greyjoy looks up at the sky and hears a roar of himself... Since he has seen the dragons for a long time, he wouldn't be scared of just a dragon. But what if there are more dragons?"

There's also a major clue hidden in the opening credits of Game of Thrones, which hints at this very theory.

In the opening credits of this week's episode, eagle-eyed fans pointed out a larger dragon pictured with three smaller dragons.

So I replayed the intro of episode 4 cos they always leave hidden messages & look at what we have! 3 small dragons & a larger dragon! Also the comet is flying over the same way when the first dragons were born! Could Drogon have laid eggs in season 5!?! #GameofThronespic.twitter.com/iWDIvIjA8A
